WlCK-RAISER FOR LAM PS-.

SPECIFICATION forming part of Letters Patent No. 513,638, dated January30, .1894.

Application filed January 11, 1893. Serial No. 457,997. (No model.)

To all whom it may concern:

Be it known that I, HIRAM W. HAYDEN, of Waterbury, in the county of NewHaven and State of Connecticut, have invented a certain new and usefulImprovement in Wick-Raisers for Lamps, of which the following is aspecification.

My improvement relates to central draft lamps.

The improvement consists in a wick raiser for such alamphavin g tworesilient arc-shaped fingers or strips constructed to engage a wick andhaving their free ends crossed and provided with projections whereby itwill be possible to disengage the wick with one hand.

In the accompanying drawings, Figure 1 is a central verticalsection ofthe upper portion of an Argand lamp embodying my improvement. Fig. 2 isanother vertical section taken in a plane at right angles to that ofFig. 1. Fig. 3 is a top view of the lamp with certain parts removed andshowing the wick raiser engaged with the wick. Fig.4. is a view likeFig. 3, except that it shows the wick raiser disengaged.

Similar letters of reference designate corresponding parts in all thefigures.

A designates the oil reservoir or tenet of the lamp.

B B designate a wick tube, which consists of two concentric shellsarranged one within the other so as to leave between them an annularspace for the wick, W. The inner shell, B, is fixed in the bottom of thereservoir, but the outer shell is connected with an air distributer C,which is removably fitted to an opening in the top of the reservoir.

D designates a wick raiser consisting of two arc-shaped fingers orstrips (1' 01 made of resilient metal,such,forinstance, as brass. At oneend, they are both, connected to a shank d This shank extends downwardly and then outwardly toward the circumference of the reservoir,being connected at its extremity to a rod 01 The rod 61 is fitted to aguide a formed in the top of the reservoir and extends through thereservoir,so that it may be reached for the purpose of adjusting thewick. The arc-shaped fingers or strips extend around the inner shell ofthe Wick tube and are intended to embrace the wick W. As shown, theirupper edges are provided with teeth for engaging with the wick. The freeends (1 d of the fingers or strips are notched and extended across eachother and bent outwardly, the extremities being made to form handles 0101 By removing the air distributor C with the outer shell 13 of the wicktube, it will become possible to raise the fingers or strips d 01 sothat their free ends will be above the reservoir, A, whereupon it willbe possible to disengage them from the wick, by simply pressing towardeach other the handles 01 d This may be done with the thumb andforefinger. "While the fingers or strips are disengaged from the wick,the latter may be adjusted to a difierent position, so that the fingersor strips when released will engage at a different point, or while thefingers or strips are wholly disengaged from the wick, a new wick may besubstituted.

It will be seen that by my improvement I produce an extremely simpleandconvenient wick raiser having the great advantage of being capable ofmanipulation with one hand for the purpose of disengaging it from awick.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In an Argand or central draft lamp, the combination of a reservoirhaving a central opening in its top, an inner wick tube shell fastenedin the reservoir, an outer wick tube shell detachably secured in thesaid central opening of the reservoir and a Wick raiser having a handleextending outside the reservoir and comprising two resilient fingers orstrips, whose free ends are crossed and constructed to form handleswhich may be manipulated with one hand to disengage the fingers orstrips from a wick, and a downwardly and outwardly extending shankconnecting said fingers or strips to their handle substantially asspecified.

2. In an Argand or central draft lamp, the combination of a reservoirhaving a central opening in its top, an inner wick tube shell fastenedin the reservoir, an outer wick tube shell detachably secured in thesaid central opening of the reservoir and a Wick raiser having a handleextending outside the reservoir and comprising two resilient fingers orstrips whose free ends are crossed and at the extremities bent outwardlyto form handles,

strips, whose free ends are notched and crossed and at the extremitiesbent outwardly to form handles, and a downwardly and outwardly ex- 1 5tending shank connecting said fingers or strips to their handlesubstantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

HIRAM W. HAYDEN.
